Rhizoma perennial peanut (RPP—Arachis glabrata Benth.) is a high quality, vegetatively propagated, forage legume introduced into southern USA from South America. Information on the performance of seed-derived lines from this germplasm is lacking. This information is needed to help determine the feasibility of establishing a recurrent selection breeding program to improve the performance of this germplasm. The objectives of this study were to evaluate the variation within Florigraze seedling progeny for reproductive and morphological traits, and to identify lines with superior agronomic characteristics. Three hundred naturally occurring seedlings of Florigraze were identified in the field and characterized for traits including floral initiation, growth habit, leaf morphology, main stem height, lateral growth, and plant density. Seven lines were vegetatively increased for forage evaluation. These lines were evaluated for 2 yr at two locations, for dry matter forage yield, forage quality, plant height, lateral growth, and stand density. None of the Florigraze lines flowered earlier than Florigraze and 22% failed to flower in 3 yr of observation. Means of lines for all morphological traits were consistently below the mean of Florigraze plants. None of the seven replicated lines outperformed Florigraze for all forage traits. Some lines were superior for forage yield or crude protein, but not across locations. If the poor performance of seed-derived lines from Florigraze is representative of RPP, then future selection and advancement of this germplasm may be seriously limited.
